This may seem like a silly question, it is, but when you put a concrete foundation or concrete poles and then want to build the rest of the structure in wood, how do you connect the concrete to the wood? It just doesn't make sense... Does it just stand on top???

Depends. For something like a perimeter wall foundation or a concrete slab J shaped anchor bolts are set in the concrete, Holes are drilled for the bottom wood plates to fit through and a large washer and nut is used to secure. There are a variety of formed metal brackets that can be used in a situation where the structure is built on concrete pillars or columns. Google Simpson Strongtie

so you sort of set some metal bars in the concrete then drill a hole in your wood and slide the metal bar through the hole in the wood and secure the whole?

That's not quite what MtnDon said. Note the "J shaped anchor bolts". These are actually a bolt that is set in the concrete when it is poured. The top of the J has the threads, the lower part of the J locks the bolt into the concrete as it hardens. When you build your exterior wall, you drill a hole in the bottom wall plate at the appropriate location, set your wall over the bolt, then tighten down the nut. The wall is then held-fast to the concrete. Note- you use several of these on each exterior wall, how many depending on the length of each wall.

or an L-bolt, which is what I really meant.
pictures are sometimes better than words
There are also minimum washer sizes; some places require 3 x 3 plate washers.
